One of the goodman condensing unit for my house starts good every thing works fine, but it runs OK for couple of hours and by then the refrigerant line connecting the unit condenses and it will not blow cool air. I have to turn it off, may be for couple of hours and start again and it works Ok till the copper line gets condensed and problem repeats

The refrigerant line is actually supposed to condensate, but if you mean "freeze up", thats a problem. The condensation occurs because the line temp is lower than the outside temp, kinda like a soda can outside. From what you described, Im pretty sure you are either over or under charged on refrigerant. The reason it will not come back on for a couple of hours is because the compressor is in "protection" mode and has to cool down before coming back on. When you are low or high on refrigerant, the compressor has to work harder which over heats and trips the internal overload switch. Have the unit charged properly and you shouldn't have a problem.
This is return air filter dirty or air not flowing over the evaporator coil do to dirt an debris. Also the reason could be low on refrigerant! Connect hoses only as a last resort once air flow is checked out!
